We have a family business and one day we found ourselves in a legal situation in which we felt completely overwhelmed and helpless. We quickly realized there’s a whole different world out there that we know nothing about. Reached out to David and he quickly wrapped himself around our case. We know he was working around the clock. In a matter of days, we had a solid argument. He is sharp, candid and a true professional. Not sure how an attorney can help a client ANY better. Absolutely no hesitation recommending him.

When I was looking for a divorce lawyer, the most important thing to me was finding someone who would be easy to communicate with. I was anticipating a nasty custody battle and the last thing I wanted was a lawyer who was hard to get a hold of or who didn’t make me feel like my case was a priority. David Costa and Robin Mann were exactly what I was looking for. They responded quickly to all of my emails, took all of my concerns very seriously and above all, is very knowledgeable about family law. This was such a difficult phase of my life and they helped me to get through to the end of it with the best possible outcome. I highly recommend this law firm.

Mr. Costa and his wonderful assistant couldn't have been anymore professional. It's unfortunate I had to meet them under these circumstances but I wouldn't have chosen anyone different to represent me if I could. They’ve always kept me up to date on things I needed to get done and both were available when I had questions. They are first class in my book.

Have utilized David's services several times over the last five years. He always is quick to respond (even when he was on vacation), knows the real estate business inside out. His expertise always gives me the confidence the deal is done right.
